Derived from the cross-section geometry by polygon integration. The published mass per meter is the catalog value; the calculated figure is a geometric cross-check. Because the modulus of FRP is about a tenth of steel's, deflection usually governs, so check spans in the profile calculator. For a planning budget per meter, enter these dimensions in the price estimator.

What a 100×6 mm fiberglass round tube carries
| Span (m) | Allowable UDL (kN/m) | ≈ lb/ft | Governing check |
|---|---|---|---|
| 1 | 12.2 | 835 | deflection |
| 1.5 | 3.9 | 265 | deflection |
| 2 | 1.7 | 115 | deflection |
| 2.5 | 0.87 | 59.6 | deflection |
| 3 | 0.51 | 34.7 | deflection |
| 4 | 0.22 | 14.7 | deflection |
| 5 | 0.11 | 7.6 | deflection |
| 6 | 0.06 | 4.4 | deflection |
Spans where the allowable load falls below 0.05 kN/m are omitted. Point loads, connections, lateral restraint and other exposures need their own check: open this section in the calculator or compare every size in the span tables.
Mechanical and physical properties
Internal catalog reference: f1-rt-014 (website reference, not a manufacturer SKU). Material dataset: E23-ISO. Revision: catalog-05fc2fc34578.
The design manual provides general-purpose E23 laminate and sizing references. No public test report is mapped to this exact section and formulation; this is not configuration certification or confirmed availability. Published catalog mass for the default dataset; confirm finished-product mass.
The methods below identify measurement standards, not proof that this section was tested. Confirm manufacturing, required performance and the applicable report before specification.

- Resin:
- Isophthalic unsaturated polyester
- Glass content:
- 65–70% by weight
- Density:
- 1.9 g/cm³
- Grade:
- E23
- Fire:
- Standard grade — not fire-retardant (specify an FR grade for ASTM E84 Class 1)
Data basis: F1-published general-purpose laminate (FRP Profile Design Manual DOC-PF-2026-EN Rev. B); ILSS 30 MPa published above the EN 13706 minimum of 25 MPa; transverse values are EN 13706-3 Table 1 grade minimums. Standard isophthalic polyester is not fire-retardant — for ASTM E84 Class 1 specify the FR-E23 grade. Compressive strength, Barcol hardness and water absorption are not specified by EN 13706 — the figures shown are typical industry values for this resin system, pending F1 certified test data; request certified values before final design.
Standards: EN 13706 Grade E23.
Values marked “Verify before release” are pending certified test data and are never estimated. Request batch-traceable certified data through the quote form before final design.

CHS 100×6: common questions
How much does a fiberglass round tube 100×6 mm weigh?
The published mass is 2.7 kg per meter (about 1.81 lb/ft), so a standard 6 m length weighs about 16.2 kg.
What load can a 100×6 mm fiberglass round tube carry?
On the published design basis (EN 13706 E23, LRFD to ASCE/SEI 74-23, outdoor exposure, L/250 deflection with shear deformation), the allowable service uniform load is about 12.2 kN/m over a simply supported 1 m span and 0.51 kN/m over 3 m (deflection governs at 3 m). Check point loads, connections and your own exposure in the calculator before release.
Is there a CAD drawing for CHS 100×6?
Yes. A dimensioned DXF cross-section is a free download on this page, with no login. It opens in AutoCAD, DraftSight, LibreCAD and other CAD packages.
What is the lead time for CHS 100×6?
CHS 100×6 is a catalog section in 6 m standard lengths. Catalog sections ship in 2–4 weeks. Catalog dimensions identify standard section options, not live inventory. Confirm tooling, material, quantity and production timing in the quotation.
